download both files connect your phone to pc and put those 2 files in N900/systemBackups folder. if there is no folder in N900 then create one.

After that open xterm and type:

Code:
root
apt-get install backupmenu
when xterm finishes installing backupmenu then restart N900 while keyboard open will boot in backupmenu and keyboard closed will boot into Maemo.

It's pdf file, there is no password.

I did check the link though and found it to be terribly slow, so I also put it in my public dropbox folder, which you can find below.

You need rootsh installed for this to work
Code:
sudo gainroot
fsck -af /dev/mmcblk0p1
mount /dev/mmcblk0p1 /home/user/MyDocs
Please post the full error messages if errors occur.

@rajanmb2005,

Just an (informed) guess. It appears that mmcblk0p1 is a VFAT partition, but is marked as being a Linux (ext3) partition.

As root, type "sfdisk -d" and post here the EXACT results.

Re: urgent -my internal memory corrupted help plz
 
dev/mmcblk0p1 should be something like ID c W95 FAT32 (LBA)

I'm not sure but I guess changing the id back with fdisk would destroy all your data on MyDocs.

Try to boot rescue mode from BackupMenu and connect to a Ubuntu 11.04 Live-CD. Then try to fix it with Gparted. forget that.

Did you installed backupmenu successfully? I mean do you get a small menu when booting your phone with keyboard open?
If so fine, just download this file
http://robbiethe1st.afraid.org/Backu...7-optfs.tar.gz
copy it to your memory card in folder systemBackups.

Then start backupmenu and choose (r) Restore a backup -> eMMC MyDocs (don't know exactly how it's listed there)
Try it and post back...

Greetz,

J4ZZ

The change of the id via sfdisk is only applied to the partition table. So that might be safe to change, unless you, at some time did not not follow one of the howtos to change the file system for the MyDocs-Partition, but only you know if you did.

Am i right, that you do not want to recover some lost files from any partition, that was deleted, but want to have a usable partition for a fresh new MyDocs? Then proceed
Code:
sudo gainroot
echo "unit: sectors
> /dev/mmcblk0p1 : start= 64, size=51199936 , Id=c
> /dev/mmcblk0p2 : start= 56631360, size= 4194304, Id=83
> /dev/mmcblk0p3 : start= 60825664, size= 1572864, Id=82
> /dev/mmcblk0p4 : start= 51200000, size= 5431360, Id= 5" > table
Note: These are two commands, first to gain root rights, second to create the file table with the right content.

Next dump it to the device
Code:
sfdisk --no-reread /dev/mmcblk0 < table
Now the Phone is ready to reboot, you still have to apply the file system to the MyDocs partition and add the fifth partition inside the extended fourth partition

Please ask if anything is still unclear.

Re: urgent -my internal memory corrupted help plz
 
restoration process ended

here im in need of another problem

my old datas in the n900 could not be deleted

saying as read only file

"unable to delete" is the prompt message

somebody aware this solve me the problem

thanks

Re: urgent -my internal memory corrupted help plz
 
Do you really feel the need for another problem:D??? Thought you had enough of fun with NitDroid...:eek:

Sorry for that cheap joke:o

Read only files and non-removable folders indicate a corrupt file system. If these files are in MyDocs folder try
Code:
sudo gainroot
umount /home/user/MyDocs
fsck -af /dev/mmcblk0p1
mount /dev/mmcblk0p1 /home/user/MyDocs
If the files are in /home/user or /opt things will get more complicated, because you need to install backupmenu and boot from either BackupMenu entry and check the file system from there OR from an external PC.

Please feel free to ask if errors occur or if further questions arise.

Re: urgent -my internal memory corrupted help plz
 
The partition table looks fine.

Did you apply the file system to the partition via command line, a remote PC or the maemo HildonFileManager?

Edit: A quick search did not reveal any solution, but to apply a fresh new file system to the partition :eek:
Is that a viable solution for you?

sorry i cant understand

The above was the one i ve done last when i follow the echo test

what should i should next waiting for the solution friend

sfdisk --no-reread /dev/mmcblk0 < table

plz expain the steps

after the above said

how should i apply to the file system to the MyDocs partition and add the fifth partition inside the extended fourth partition

Re: urgent -my internal memory corrupted help plz
 
Before the explanation, i would still ask you to clarify, what you want to achieve:
1.Do you want to recover files on the former large MyDocs-partition
or
2.Do you do not care about any data on that partition and just want to move on?

Explanation:
The sfdisk utility does not actually change anything on the internal card itself. It just creates or reads the partition table and offers the information to the kernel and the other utilities. You will have to create a fresh new file system every time you change the size of any partition or create new partitions. You do that with the mkfs.-$FILESYSTEM utilities, like mkfs.vfat.

Basic steps:
1.Create the table, like the echo command to create the file
- echo is a simple command to create text inside the "-characters, here, to a file, therefore >$FILENAME

2.Write the information from the file to the first sector of the internal card via the sfdisk command
- sfdisk is the low level utility to access the first sectors of a sd-card like /dev/mmcblk0, --no-reread option tells sfdisk to do just that, do not try to read the partition table, because it would be useless right now, and table is the name of the file, which holds the information from which sfdisk reads

3.Reboot to have the changed geometry be known to the kernel

4.Now actually apply the file system, also named: format the partition

your explanation are good

but i need the steps to follow

i don't care about any data on that partition and i just want to move on?

steps plz

Re: urgent -my internal memory corrupted help plz
 
Steps 1 and 4 assume, that you are still trying to install Nitdroid at some time on a separate partition. If you have some other plan please demand new directions ;)

All steps should be done as root

Step 1
Code:
echo "unit: sectors
 > /dev/mmcblk0p1 : start= 64, size= 51199936, Id=c
 > /dev/mmcblk0p2 : start= 56631360, size= 4194304, Id=83
 > /dev/mmcblk0p3 : start= 60825664, size= 1572864, Id=82
 > /dev/mmcblk0p4 : start= 51200000, size= 5431360, Id= 5
> /dev/mmcblk0p5 : start= 51200016, size= 5431344, Id=83" > table
Step 2
Code:
sfdisk --no-reread /dev/mmcblk0 < table
Step 3
Code:
reboot
Wait for the device to reboot, then
Step 4
Code:
mkfs.vfat -n MyDocs /dev/mmcblk0p1
mke2fs -L NITDroid -j -m0 /dev/mmcblk0p5

Half a success :(
The MyDocs partition is not formatted. Please try again
Code:
sudo gainroot
umount /dev/mmcblk0p1
mkfs.vfat -n MyDocs /dev/mmcblk0p1
mount /dev/mmcblk0p1 /home/user/MyDocs

Re: urgent -my internal memory corrupted help plz
 
1st I'd like to say I really like your attitude ;)

So, your thread should be this one and you should be fine using NITDroid-Installer_0.2.8-8.deb

Simply download the file to your phone and click on it... That's all.

Greetz,

Time for a file system check!
Code:
